Embodiment Construction
[0021] refer to figure 2 , the antenna of the present invention is mainly composed of a radiation unit 1, a dielectric material 2, a floor 3 and a coaxial line 4, the antenna medium 2 is composed of people's clothing, the radiation unit 1 is vertically fixed on the surface of the clothing, and the floor 3 is symmetrically fixed on the radiation unit 1 The underside of the garment where it is held vertically.
[0022] refer to image 3 , the radiation unit 1 adopts a four-layer integrated button-type metal structure, and the height and size of the four-layer integrated button-type metal structure are different. The first layer 101 adopts a hollow cone, and the bottom surface of the cone has a circular through hole. The radius of the upper circle of the cone of the first layer 101 is greater than the radius of the lower circle, which is a cone with a wide top and a narrow bottom. The second layer 102 adopts a hollow cylinder, the radius of the second layer 102 cylinder is the...

The invention discloses a wearable type ultra-wideband antenna which mainly solves the problems that the existing antenna cannot cover an ultra-wideband frequency range, is light in weight and is not easy to wear. The antenna is composed of a radiation unit (1), an antenna medium (2), a floor (3) and a coaxial wire (4), wherein the antenna medium is composed of human clothes and the radiation unit is fixedly arranged on the surface of the clothes; the floor is symmetrically fixed on the bottom surface of the clothes, on which the radiation unit is vertically fixed; the radiation unit and the floor are respectively connected with an outer core and an inner core of the coaxial wire to feed, wherein the radiation unit is composed of four layers of integral button type metal bodies; the first layer (101) is a hollow cone which is provided with circular through holes on the bottom surface; the second layer (102) is a hollow cylinder; the third layer (103) is a cuboid; and the fourth layer (104) is a regular hexagonal prism which is provided with a through hole (105). The coaxial wire can feed the radiation unit by a circular hole (301) in the center of the floor. The wearable type ultra-wideband antenna disclosed by the invention has the advantages that the ultra-wideband frequency range can be covered and the weight is light.
Description
technical field [0001] The invention relates to the technical field of wireless communication, and relates to an antenna, in particular to a wearable ultra-wideband antenna. technical background [0002] Ultra-wideband technology began with the pulse communication technology that emerged in the 1960s. It uses ultra-short pulses with extremely wide spectrum for communication, also known as baseband communication and carrier-free communication. It is mainly used in military radar, positioning and communication systems. In February 2002, the U.S. Federal Communications Commission FCC approved UWB technology for civilian use. Due to the characteristics of high transmission data rate, strong anti-multipath interference ability, high confidentiality, and beneficial to multi-functional integration, UWB antenna has become one of the technologies with great competitiveness and development potential in short-distance wireless communication. It has attracted the great attention of man...
